Hybrid Tea rose plant named `JACnor`

ABSTRACT

A new and distinct variety of rose plant of the Hybrid Tea class, having an upright, vigorous growth habit; good flower form; large, dark green foliage; and an attractive pink blend flower color.

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class which was originated by me by crossing the variety JAColite, U.S Plant Pat. No. 4,167, with the variety First Federal's Reinaissance, U.S. Plant Pat. No. 4,459.

The primary objective of this breeding was to produce a new rose variety having the upright, vigorous growth, good flower form and rapid repeat bloom of the female parent combined with the long bud, large foliage and early bloom of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Excellent hybrid exhibition tea flower form.

2. Vigorous, upright growth habit.

3. Attractive rose pink and light pink blend flower color.

4. Large, dark green semi-glossy foliage.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

Parentatge:

Seed parent.--JAColite, U.S. Plant Pat. No. 4,167.

Form.--When first open: High centered. Permanence: Retains its form to the end, outer petals curl back.

Petalage.--Number of petals under normal conditions: 30-35.

Color.--The upper side of the petals is Red Group 45C on the petal edges and Red Group 48C to D elsewhere. The reverse side of the petals is Red Group 48C to D with Red Group 45C on the petal edges. The base of each petal has a greenish-white 1/4"×1/4" half moon at the point of attachment. The major color on the upper side is Red Group 48C to D.

Variegations.--None.

Discoloration.--The general tonality at the end of the first day: No change. At the end of the third day: No change.

Fragrance.--Moderate.

Petals:

Texture.--Thick and leathery.

Shape.--Round.

Form.--Tips slightly recurved, edges slightly quilled.

Arrangement.--Imbricated, with few petaloids in the center.

Lastingness.--On the plant: Long (7 days). As a cut flower: Long (8-9 days).

Reproductive parts:

Anthers.--Size: Medium. Quantity: Many. Color: Yellow. Arrangement: Regular around styles.

Filaments.--Color: Yellow with red at their base.

Pollen.--Color: Lemon yellow.

Styles.--Color: Red.

Stigmas.--Color: Greenish-white.

I claim:
 1. A new and distinct variety of rose plant of the Hybrid Tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its vigorous, upright growth habit; its large, dark green foliage; its attractive pink blend flower color; and its excellent, high-centered exhibition flower form.
